Executive SummaryUpdated on Sep 21, 2025

Splunk Enterprise Security and OpenText Enterprise Security Manager are both significant contenders in the enterprise security industry. Splunk tends to have an advantage with its user-friendly interfaces, extensive automation, and strong integration capabilities that facilitate rapid threat response. In contrast, OpenText is noted for its robust log management and scalability, especially suited for complex systems.

Features: Splunk Enterprise Security offers comprehensive threat detection with customizable dashboards, integration with the MITRE ATT&CK framework, and robust data handling. It boasts a powerful search processing language, real-time monitoring, and advanced alerting. OpenText Enterprise Security Manager excels in integrating with legacy systems, delivering strong correlation capabilities, and offering real-time monitoring, though it may lack some of Splunk’s extensive customization options.

Room for Improvement: Splunk users often cite a steep learning curve and high costs as concerns, along with a need for enhanced AI integration and improved pricing models. There is also a desire for better alert management. OpenText users highlight the need for improved threat intelligence integration, better SOAR capabilities, and a more streamlined user interface for modernized threat detection.

Ease of Deployment and Customer Service: Splunk is recognized for flexible deployment options across cloud, hybrid, and on-premises environments, supported by extensive documentation. Customer support experiences can vary. OpenText supports diverse deployment environments, with a focus on on-premises setups, and is noted for its complexity and reliance on professional services with moderate technical support.

Pricing and ROI: Both Splunk and OpenText offer premium pricing models. Splunk’s volume-based pricing, tied to data ingestion, can be costly but is justified for larger organizations requiring advanced security measures. OpenText, which typically utilizes event-based pricing, provides strong ROI in large enterprise environments, though more flexible licensing could enhance accessibility and appeal.

The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.

Featured Reviews

Ramnesh Dubey - PeerSpot reviewer
Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods
The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.

Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.
